Getting the best dies in the market is one of the most critical factors to ensure success. Several materials are used to produce dies. One needs to understand the type of services they require to help determine the kind of dies material to use for projects. Two main processes are involved in the preparation of dies.
Hot chamber die casting
The process utilizes alloys under low melting temperatures to produce high-precision die cast products. In this method, the chamber cannot accommodate alloys with high melting points, damaging the casting machine.
The chamber machine has an alloy melting pot embedded into the machine to improve its functionality. The injection cylinder plunger of the machine rises to make way for the molten metal to fill the chamber. A pressure of about 700psi to 5000psi is exerted on the casting to hold it in place as the plunger travels towards the cover die. The plunger then retracts after the metal has solidified in the cavity.
An example of the types of die products in the hot chamber includes custom zinc die casting, containing multiple metals. Zinc die is mainly used as it is an economical material that is easy to cast. The hot chamber die casting takes an average of fifteen cycles per minute, and the final process of molten forming takes about fifteen to twenty minutes.
Some of the advantages of using hot chamber die casting include;
- Speeded cycling production
- Reduced porosity
- Efficient processes
- Reduced metal wastage
- Long-lasting types of machinery
Cold chamber pressure die casting
Cold chamber pressure die casting is best used when one wants precise and accurate castings. It is recognized as one of the ways that ensure high-quality die casting products for special projects. This method is best applied for die casting alloys with a high melting point, such as copper and aluminum. In addition, cold chamber pressure die casting produces denser and stronger metals for long-lasting purposes.
Custom aluminum dies casting is a unique die casting that can be processed through hot and cold chamber processes. Die casting made from aluminum is first molted with high-pressure techniques, giving it denser and more robust.
Multi-slide die casting
Multi-slide die casting employs four slides that are perpendicular to produce accurate castings. In most cases, multi-slide die casting is used for high-performance and flexible controllers.
Computer numerical control machine
Computer numerical control machine, also known as custom CNC machining services, is the process of manufacturing in which a pre-programmed computer system dictates tools from the factory. The computer numerical control machine is in charge of various machinery with a processing company. CNC machining is composed of several processing steps that help improve the functionality.
The first step in CNC machining involves designing the products. In designing, CAD software is used to help with the precision of the properties and dimensions. The CAD software must coincide with the computer-aided machinery to ensure consistency of the work. Computer-aided machinery eliminates errors in the program to produce a program that guides the movement of the machines in the manufacturing process. The CAM software also helps determine how to place parts concerning the raw materials used, which helps maximize materials and save on wastage.
Custom computer numerical control
In addition to the various die casting services, you also get custom CNC cutting machining services that fit your requirements. Expert engineers conduct custom CNC cutting to ensure that the desired goal is achieved.
In conclusion, going for hot chamber products or products from a cold chamber depend on the material one intends to use. Cold chambers produce machinery that stays cooler hence handling metals with a high melting point, and also the products have superior properties with a smooth finish. Products from the cold chamber require more pressure to be applied during processing to fill the chamber. Therefore, both cold and hot chamber die casting can be used to produce precise castings.
